Classes
Declar ation Example
public members are accessible from anywhere the class is
visible.
private members are only accessible from the same class
or a friend (function or class).
protected members are accessible from the same class,
derived classes, or a friend (function or class).
constructors may be overloaded just like any other
function. You can define two or more constructors as long
as each constructor has a different parameter list.

Inheritance
Inheritance allows a new class to be based on an existing
class. The new class inherits all the member variables and
functions (except the constructors and destructor) of the
class it is based on.

Operator Overloading
C++ allows you to define how standard operators ( , , ,
etc.) work with classes that you write. For example, to use
the operator with your class, you would write a function
named for your class.
Exampl e
Prototype for a function that overloads for the
class:
If the object that receives the function call is not an instance
of a class that you wrote, write the function as a friend of
your class. This is standard practice for overloading and
.
Exampl e
Prototype for a function that overloads for the
class:
Make sure the return type of the overloaded function
matches what C++ programmers expect. The return type of
relational operators ( , , , etc.) should be , the
return type of should be , et c.
